DUM PING-CAR.

SPECIFICATION .forming part of Letters Patent No. 722,100, dated March 3, 1903. Application filed .Tune l2, 1902. Serial No. 111,365. (No model.)

To a/ZZ whom it may concern:

Be it known that I, JOSEPH L. HAMEL, a citizen of the United States, residing at Grafton, in the county of Walsh and State of North Dakota, have invented new and useful Improvements in Dumping- Cars, of which the following is a specification.

This invention relates to dumping-cars, and has for its object to provide means for releasing the contents of a car through the bottom thereof through the medium of a plurality of valves controlled by suitable mechanism.

The peculiar construction of this invention will be clearly described hereinafter and illustrated in the accompanying drawings, in which- Figure 1 is a bot-tom plan view of the car equipped with the Valves in accordance with my invention. Fig. 2 is a vertical longitudinal sectional view of a car having the valves applied. Fig. 3 is a similar view of one of the valves in its seat, and Fig. 4 is a crosssection of the same.

The reference-numeral 1 designates a car in the bottom of which is provided a plurality of slots or openings 2. Under each opening is provided a valve-casing 3, provided with a longitudinal bore 4 and diametrically oppositely located slots 5 and 6, located in alinement with the slots 2 in the bottom of the car. Revolubly secured within each casing and seated in the bore thereof is a valve 7, having a longitudinal slot 8,adapted to aline with the slots heretofore described, and on the end of each valve is provided a bevel-gear 9. Transversely arranged on the bottom of the car are shafts 10 and 1l, to which are keyed beveled gears 12 at suitable intervals along the shaft, so as to mesh with the bevelgears on the Vertical shafts 13 and 14 are journaled to the sides of the car and carry gears at their respective ends, (designated by the reference-numerals 15 and 16.) The bevel-gears 15 mesh with the gears on the transverse shafts, while the gears 16 at the top of the vertical shafts are in mesh with toothed hand- Wheels 17 and 18, journaled near the top of the car, so that by turning said hand-Wheels motion will be imparted to the vertical shafts and therethrough to the transverse shafts which are in mesh with the gears on the valves and are adapted lto control the valves toopen or close the openings in the bottom of the car.

B v reference to Figs. l and 2 it will be noticed that the gearing on the bottom of the car may be arranged to suit the convenience of the builder and that two or more valves may be in mesh with a single gear-wheel on the transverse shaft, whereby all of the slots may be closed oropened simultaneously.

While I have illustrated the preferred form of the arrangement of mechanism for operating the valves, I do not limit myself to the exact details of construction shown, but reserve the right to make such slight changes and alterations as would suggest themselves from time to time and still be Within the scope of the claims.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a dumping-car, the combination with the bottom thereof, having a plurality of openings,of valve-casings positioned immediately below the same and provided with registering slots, Valves seated in said casings and also having slots adapted to aline with the first-named slots, beveled gears on the end of each shaft, a transverse shaft arranged adjacent the bottom of the car,gearwheels carried by said shaft and adapted to mesh with the gears on the valve and means for r0- tating the transverse shafts whereby the valves may be operated.

2. In a du mping-car, the combination with the bottom thereof, having a plurality of openings,of valve-casings positioned immediately below the same and provided with registering slots, valves seated in said casings and also having slots adapted to aline with the first-named slots,.beve1ed gears on the end of each shaft, a transverse shaft arranged adjacent the bottom of the car, gear-Wheels carried by said shaft and adapted to mesh with the gears on the valve, a vertical shaft I and thence to the transverse shaft so as to arranged adjacent the side of the ear, a bevoperate the Valves. xo eled gear on the lower end of said shaft and In testimony whereof I afx my signature adapted to mesh with the gear on the transin presence of two Witnesses.
